A Comparative Analysis of High-Rise Building Shapes and Orientations on the Performance and Energy Generation of Building Integrated Photovoltaic Systems in Tehran

This study aims to evaluate the impact of high-rise building shape and orientation on the amount of solar energy received by their facades. Additionally, it seeks to determine the optimal building shape for energy generation, utilizing photovoltaic panels that can be seamlessly integrated into various facades. One promising solution is the implementation of building-integrated photovoltaics (BIPV), which not only generates clean electricity but also offers a seamless integration into the building’s design. The objectives of designing BIPV are to meet the building’s energy requirements while simultaneously reducing CO
2
emissions. The feasibility of this system has been confirmed through the use of PVsyst software. Based on the findings of this study, Y-shaped tripartite buildings have been determined to be the most effective form, generating $3433 \mathrm{kWh} {/}$ year. Furthermore, this Y -shaped design has the potential to reduce annual $\mathrm{T C O}_{2}$ emissions by 5904.
